I have always been under the assumption that some sort of percentage of people cheat the system. I am sure with a more strict drug testing regiment like cycling has you would find more of them. This current system is not equipped to deal with the technology of the cheating programs.

I would not be surprised if people were doing them and if they were not doing them. We might never know. Internal testing leaves the published results up to the person in charge.

Come on guys, no sport can avoid it, especially with this level of media coverage we have now.
We cannot know who is using but there are PED in the sport.
And the level of athleticism required is so high for the Crossfit Games (even at the regional level).
You don't bring a knife to a gunfight.
